Oil film thickness measurements made in the front main bearing of an operating 3.8 L, V‐6 engine were compared with rheological measurements made on a series of commercial and experimental oil blends. High‐temperature, high‐shear‐rate viscosity measurements correlated with the film thickness of all single‐grade and many multigrade oils. However, the film thickness provided by some multigrade oils were larger than could be accounted for by their high‐temperature, high‐shear‐rate viscosities alone. Although the pressure/viscosity coefficients of some of the oils were significantly different from those of the majority of oils tested, they were not oils which produced unusual film thicknesses. As a consequence, correcting oil viscosities for the esimated pressures acting within the bearing was unsuccessful in improving the correlations. The correlations were improved, however, by accounting for the elastic properties of the multigrade oils. Measurements of oil relaxation times at high temperatures and shear rates showed large differences in elastic properties among the test oils. A good correlation (R2 = 0.73) was obtained from a multiple linear regression of film thickness as a function of both high‐temperature, high‐shear‐rate viscosities and relaxation times.

The classics will circulate wrote a public librarian several years ago. She found that new, attractive, prominently displayed editions of literary classics would indeed find a substantial audience among public library patrons.

‘WORK STUDY specialists of Europe—from both the Six and the Seven— are getting together in London this year regardless of what happens to other meetings,’ said Mr. R. M. Currie, C.B.E., President of the European Work Study Federation, in a statement on the forthcoming Congress of the Federation which is to take place at Church House, Westminster, from May 20 to 23.

The initial shock of devaluing the currency, after so many promises that it would not take place, has passed; only the uncertainty and apprehension remain. It seems an idle exercise to compare the present state of the country's economy with other periods in recent history, such as when in the first Labour Government, we went off the gold standard; at that time, shock was indeed profound and again, the French were cock‐a‐hoop, but the position was complicated by the huge inter‐indebtedness of the Allies in the First War. Or the first devaluation after the Second World War, but both periods were also characterized by public waste and profligate spending. Now, we have to obtain foreign loans and financial backing to keep going, and it is this aspect of the present devaluation which will probably far outweigh any positive advantages. The country's massive external debts were increased by approximately one‐seventh overnight, probably wiping out completely all the repayments made at such great effort since the War. Devaluation of the currency cannot be seen as anything but a grievous blow to the country, presaging hard times ahead for everyone. When promises were being made that devaluation would not take place, there can be little doubt that these were honestly made and, at the time, believed in, for no Government of a country with imports always exceeding exports, would impose such a burden on its people willingly. It must then have been forced upon them.

HAS BRITAIN really lost its sense of purpose? Has it no noticeable industrial policy?

The very headline of this presentation hints at least two things. First, what is meant is the history of American sociology, though it is some what awkward to say so outright. Second, the history of American sociology is accomplished, in an impor tant sense, but one should not say that so out‐right, either. In philosophy, as Wittgenstein advised, whereof we can not speak, thereof we must be silent. A different rule reigns in sociology: whereof we can hint at, thereof we must prove. My first task, there fore, is to prove that no matter how embarrassing it may seem one canspeak of a his tory of American sociology after all. My second task is to prove that it has already been on a course of development specifically characteristic of it. And, finally, my last point will be that this specific course is brought to its desired end. Every thing in its own time. Talking about the history of American sociology is extremely risky. But it is the risk that it makes it worth trying. Part of the risk stems from the issue if there is a history of sociology at all, as well as from the issue if there is American sociology in the proper sense of the word. Apart from this, there is the consideration that it may be the American nature proper of that sociology that makes it the least likely to have its own history. First things first.

Joan undertook the ground-breaking project originally reported in the 1958 pamphlet, Management and Technology, not at one of Britain's great universities, but at the unfashionable address of the South East Essex Technical College (then in the county of Essex but now part of the London Borough of Barking and Dagenham). The Human Relations Research Unit had been set up at the college, which is now part of the University of East London, in 1953 with support from a number of agencies including funding ultimately derived from the Marshall Plan. Its express purpose was to enhance the performance of industry and commerce through the application of social science. Those readers familiar with the area will know that, at the time, it was economically and culturally dominated by the Ford assembly plant in nearby Dagenham, but it was also home to a diverse range of small- and medium-sized industrial workshops that were typical of the pre-war Greater London economy (Woodward, 1965; Massey & Meegan, 1982). It was into this diverse industrial milieu that Joan and her research team ventured (Fig. 1), completing their main study in 1958.
